Question

Macy is feeding the pigeons at her local park. The number of pigeons around her doubles every 15 minutes. The following function represents the number of pigeons around her after x minutes.

P(x)=5(2^x/15)


Which statement is true?

The expression, (0.133)^x, reveals the approximate rate of increase of the pigeons per hour.

The expression, (1.047)^x, reveals the approximate rate of increase of the pigeons per minute.

The expression, (0.133)^x, reveals the approximate rate of increase of the pigeons per minute.

Answer 1

Use the properties of exponents to rewrite the function.

P(x)=5(2^x15)

=5(2^1/15)^x

=5(1.047)^x


In the expression, 5 represents the initial number of pigeons, and (1.047)^x reveals the rate of increase.

Therefore, the expression, (1.047)^x, reveals the approximate rate of increase of the pigeons per minute.

Answer 2

so its B
